Function Documentation

void freenect_set_audio_in_callback ( freenect_device dev,
freenect_audio_in_cb  callback 
)

Set the audio in callback. This is the function called when the library has new microphone samples. It will be called approximately 62.5 times per second (16kHz sample rate, expect 512 samples/callback)

Parameters
devDevice for which to set the callback
callbackCallback function to set

Definition at line 142 of file audio.c.

void freenect_set_audio_out_callback ( freenect_device dev,
freenect_audio_out_cb  callback 
)

Set the audio out callback. This is the "tell me what audio you're about to play through the speakers so the Kinect can subtract it out" callback for a given device. If you choose not set an audio_out_callback, the library will send silence to the Kinect for you - it requires data either way.

Parameters
devDevice for which to set the callback
callbackCallback function to set

Definition at line 145 of file audio.c.

int freenect_start_audio ( freenect_device dev)

Start streaming audio for the specified device.

Parameters
devDevice for which to start audio streaming
Returns
0 on success, < 0 if error

Definition at line 149 of file audio.c.

int freenect_stop_audio ( freenect_device dev)

Stop streaming audio for the specified device.

Parameters
devDevice for which to stop audio streaming
Returns
0 on success, < 0 if error
